...surprise, though still a shock, when in 1990 doctors found she had ovarian cancer. Thanks to aggressive surgery and intensive chemotherapy, Fisher, a 41-year-old dietitian living in Pittsburg, California, made a remarkable recovery and became tumor-free. But she knew her future was still menacing. Scientists had recognized for several years that ovarian and breast cancer sometimes ran together in families, as if linked in some way. Fisher's oncologist proposed a once unthinkable step: a "prophylactic" double mastectomy. Removing her breasts, the doctor said, could save her life...
...vectors may not have to be viruses. Some researchers are working on ways to inject DNA directly into human cells. To treat patients with malignant melanoma, a deadly skin cancer, a team led by Dr. Gary Nabel at the University of Michigan encased a tumor-fighting gene in liposomes, harmless little bubbles of fat. The genes found their way into the proper cells, and in at least one case the tumors shrank...
...Michigan's Dr. Gary Nabel, the researchers treated five patients with melanoma, a deadly skin cancer. The tumors were injected with the gene HLA-B7, which produces a protein that can help the immune system fight the cancer. In all five patients, the genes safely entered the tumor cells and began making protein, and in one case the tumors shrank. The technique is no miracle cure, but the experiment adds a promising new weapon to the arsenal of genetic medicine...
...hunch was confirmed with the publication this summer of several scientific journal articles. According to the articles, tumor cells from patients with the inherited form of colon cancer bore a base pair sequence similar to that carried by the yeast mutants he was studying...
...physicians caution that taxol is not a cancer cure. "I've been giving it to patients who won't be cured by it," says Dr. Louis J. Ayash, an instructor in medicine at the Medical School. "It will never clearly get rid of the tumor...
